Supported Air Conditioners
MiniHPC is compatible with GREE air conditioners and other OEM brands under this label (e.g., Sinclair). Only residential air conditioner models are compatible, such as Gree Bora, Pular, Amber, Fairy, and Clivia. Sinclair models include Ray, Marvin, Terrel, Keyon, and Spectrum.
When selecting a suitable model, it is important to focus on a few key details that the outdoor unit should have to ensure maximum efficiency and year-round heat demand coverage.
The most important parameters are:
- Outdoor temperature range during heating. The lower limit, which can be between -15°C and -30°C, is not as crucial as the upper limit. The upper limit determines whether the air conditioner can heat DHW even on hot summer days.
- EEV. An electronic expansion valve ensures higher efficiency across a wider range of outdoor temperatures compared to a capillary tube.
- Heated outdoor unit base tray. Condensate collected during defrosting may freeze in the base tray during extreme frosts. An electric heater solves this problem.
- Size and weight of the heat exchanger. It is advisable to choose an air conditioner with the largest possible heat exchanger, preferably a two-row type (e.g., a specification of 2-1.4 indicates a two-row exchanger with 1.4mm fin spacing). Larger heat exchangers freeze more slowly, contributing to higher COP in freezing fog conditions. The weight of the air conditioner can also serve as a good indicator.
- Power limitation. Some models (such as Gree Clivia) offer this feature, which allows limiting the maximum power output during transitional periods or freezing fog conditions to reduce freezing and increase COP.

Please verify the above air conditioner parameters with your dealer before purchase, as they may vary depending on the configuration selected by the manufacturer.
Multi-split air conditioners are also supported, but this setup is not recommended. For example, in summer, a standard indoor unit might be in cooling mode on one output, while a heat exchanger with MiniHPC is connected to another output. If MiniHPC requests DHW heating, it will not be able to switch to heating mode since the indoor unit is already operating in cooling mode, potentially causing heat to be drawn from the DHW tank.
